Question

Bella is buying balloons for a back to school celebration. She sees there are 4

Answer 1

Answer:

The first unit price ($0.30/balloon) beats the second ($0.32/balloon).

Step-by-step explanation:

4 packages of 15 balloons for $18 works out to 1 package of 15 balloons for $18/4, or $4.50.  That'd be

$4.50

---------------- = $0.30/balloon.

15 balloons

Next:  5 packages of 10 for $16 works out to 1 package of 10 for $16/5, or

1 package of 10 for $3.20.  That'd be

  $3.20

----------------- = $0.32/balloon

10 balloons

The first unit price ($0.30/balloon) beats the second ($0.32/balloon).

If Bella understands the math involved in finding unit costs and actually does the work prior to buying anything, then I'm comfortable with her buying habits.

Answer 2

Answer:

The first deal is better because it has more balloons for not too much of a price (individually)

Step-by-step explanation:

15*4= 60

60/18= 3.33

Deal 1= 3.33 for each balloon

10*5= 50

50/16=3.125
